JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 253,225, dated February7, 1882.

Application tiled J une .'50, 1881.

To all whom it may concern:

Be it known that l, SIMON E. PETTEE, of Oleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Anti-Friction Journal- Boxes, and I do hereby declarethe following ,to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to anti-friction journal boxes or bearings, and itconsists in surrounding a sleeve withv a series of rollers which arefree to revolve around their own centers and around said sleeve within acasing or box.

In the drawings, Figure I is a plan view of my journal-box, showing therelative arrangement of rolls. Fig. 2 is a section of the same, taken onthe line x a', Fig. 1.

A is a box or casing, which is provided with two grooves, a a, on itsinternal circumference. (Represented by dotted lines in Fig. l.)

B is a sleeve, which is provided on its periphery with two grooves, b b,which correspond with the grooves a a in casing A.

C, O', O2, C3, and O4 are large rollers, which are provided with anges dd at their ends, said anges being so formed as to run freely in thegrooves a a and b b. These rollers are made of such size and shape thatthey tit snugly between the outside of the sleeve B and the inside ofthe casing A, and still rcvolve freely within said space.

c, c', c2, c3, and c4 are small intermediate rollers, each of which isprovided with an annular projection, e, which lits between .the endflanges, d d, ofthe large rollers O, O', O2, O3, and O4. These smallrollers c, c', c2, c3, and c4 are placed between the large rollers O,O', O2, O3, and O4, and serve to keep said large rollers from contactwith each other, and as they revolve in an opposite direction from thelarge rollers O, O', OZ, O3, and O4, it is obvious that there will benofrictional contact between them. These smaller rollers c, c', c2, c3,and c4 are provided with annular grooves g at their outer end, in whichrests a circular band, f, said band serving to keep the said smallrollers in (No model.)

-and thus by removing said caps facilitate the removal or replacement ofthe band f.

It is obvious that the flanges el and c on the rollers O O O2 O3 G4 andc c c2 c3 c4 may be larger or smaller, and the grooves a a and b l) mayalso be altered in shape and size, it only being essential that thegrooves in the casing .A and sleeve B correspond to the flanges on therollers O O O2 O3 O4, and that the projection on the small rollers c cc2 c3 c4 correspond with the shape ofthe space between theflanges ot'the larger rolls. Thus it will be seen that the rollers and sleeve,while being allowed to revolve freely, are kept from any lateraldisplacement by means of the grooves and ljanges, and a compact andnoiseless anti-friction journal is provided.

l. In an anti-friction journal-box, the combination, with the axle D andcasing A, provided with annular grooves a a, of the sleeve B, providedwith a smooth periphery and with annular grooves b b, and anti-frictionrollers interposed between' the sleeve and casing, a portion of saidrollers being provided with collars which lit within the grooves a a bb, substantially as set forth.

2. In an anti-friction journal-box, the combination, with the axle D andcasing A, the

latter provided with annular grooves a a, of

the sleeve B, having smooth' periphery and provided with grooves b b,and the large and small anti-friction rollers interposed between thesleeve and casing, the large rollers being provided with collars thatlit in grooves a a b I) and the small rollers provided with enlargedportions that lit between the collars on the large rollers,substantially as set forth.

In testimony whereot I have signed my name to this specification in thepresence ot' two subscribing witnesses.
